SOLID-STATE, TWO-LEVEL, HIGH-POWER MASER

Abstract

Theoretical and experimental investigations were continued on pulsed microwave generation without an rf input signal. Initial tests were run on two models of the pulsed generator, using a diskshaped sample without an rf input signal, without success. Measurements were made on these devices which, it was believed, showed reasons for the negative results. Equations describing the motion of the magnetization in the disk-shaped sample under the influence of a transient magnetic field, whose amplitude and direction changes with time, were programmed on an analog computer. Development of components for a K-band, high-efficiency generator, using an X-band rf input signal, continued. The first model of a low-pass filter for this generator, using a nonlinear dielectric element, was tested. The results were favorable, showing a stop-band without spurious responses. The corona problem on the 100 kilogauss pulse field apparatus also received some attention. (Author)
